Constants

Hide inherited constants

Constant Value Description Defined By
SAME_SITE_LAX 'Lax' SameSite policy Lax will prevent the cookie from being sent by the browser in all cross-site browsing context during CSRF-prone request methods (e.g. POST, PUT, PATCH etc). E.g. a POST request from https://otherdomain.com to https://yourdomain.com will not include the cookie, however a GET request will. When a user follows a link from https://otherdomain.com to https://yourdomain.com it will include the cookie yii\web\Cookie
SAME_SITE_NONE 'None' SameSite policy None disables the SameSite policy so cookies will be sent in all contexts, i.e in responses to both first-party and cross-origin requests. E.g. a POST request from https://otherdomain.com to https://yourdomain.com will include the cookie. Note: If sameSite is set to None, the secure attribute must be set to true (otherwise the cookie will be blocked by the browser). yii\web\Cookie
SAME_SITE_STRICT 'Strict' SameSite policy Strict will prevent the cookie from being sent by the browser in all cross-site browsing context regardless of the request method and even when following a regular link. E.g. a GET request from https://otherdomain.com to https://yourdomain.com or a user following a link from https://otherdomain.com to https://yourdomain.com will not include the cookie. yii\web\Cookie

Property Details

Hide inherited properties

$domain public property

Domain of the cookie

public string $domain = ''
$expire public property

The timestamp or date at which the cookie expires. This is the server timestamp. Defaults to 0, meaning "until the browser is closed" (the same applies to null).

public integer|string|DateTimeInterface|null $expire = 0
$httpOnly public property

Whether the cookie should be accessible only through the HTTP protocol. By setting this property to true, the cookie will not be accessible by scripting languages, such as JavaScript, which can effectively help to reduce identity theft through XSS attacks.

public boolean $httpOnly = true
$name public property

Name of the cookie

public string $name = null
$path public property

The path on the server in which the cookie will be available on. The default is '/'.

public string $path = '/'
$sameSite public property (available since version 2.0.21)

SameSite prevents the browser from sending this cookie along with cross-site requests.

See https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite for more information about sameSite.

public string $sameSite = self::SAME_SITE_LAX
$secure public property

Whether cookie should be sent via secure connection

public boolean $secure = false
$value public property

Value of the cookie

public string $value = ''

Method Details

Hide inherited methods

__call() public method

Defined in: yii\base\BaseObject::__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name string

The method name
$params array

Method parameters
return mixed

The method return value
throws yii\base\UnknownMethodException

when calling unknown method

 

                public function __call($name, $params)
{
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call init().

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
public void __construct ( $config = [] )
$config array

Name-value pairs that will be used to initialize the object properties

 

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}
__get() public method

Defined in: yii\base\BaseObject::__get()

Returns the value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

See also __set().

public mixed __get ( $name )
$name string

The property name
return mixed

The property value
throws yii\base\UnknownPropertyException

if the property is not defined
throws yii\base\InvalidCallException

if the property is write-only

 

                public function __get($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        return $this->$getter();
    } elseif (method_exists($this, 'set' . $name)) {
        throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
    }
    throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
__isset() public method

Defined in: yii\base\BaseObject::__isset()

Checks if a property is set, i.e. defined and not null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

See also https://www.php.net/manual/en/function.isset.php.

public boolean __isset ( $name )
$name string

The property name or the event name
return boolean

Whether the named property is set (not null).

 

                public function __isset($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        return $this->$getter() !== null;
    }
    return false;
}
__set() public method

Defined in: yii\base\BaseObject::__set()

Sets value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

See also __get().

public void __set ( $name, $value )
$name string

The property name or the event name
$value mixed

The property value
throws yii\base\UnknownPropertyException

if the property is not defined
throws yii\base\InvalidCallException

if the property is read-only

 

                public function __set($name, $value)
{
    $setter = 'set' . $name;
    if (method_exists($this, $setter)) {
        $this->$setter($value);
    } elseif (method_exists($this, 'get' . $name)) {
        throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);
    } else {
        throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
    }
}
__toString() public method

Magic method to turn a cookie object into a string without having to explicitly access $value.

if (isset($request->cookies['name'])) {
    $value = (string) $request->cookies['name'];
}
public string __toString ( )
return string

The value of the cookie. If the value property is null, an empty string will be returned.

 

                public function __toString()
{
    return (string) $this->value;
}
__unset() public method

Defined in: yii\base\BaseObject::__unset()

Sets an object property to null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($object->property).

Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.

See also https://www.php.net/manual/en/function.unset.php.

public void __unset ( $name )
$name string

The property name
throws yii\base\InvalidCallException

if the property is read only.

    if (method_exists($this, $setter)) {
        $this->$setter(null);
    } elseif (method_exists($this, 'get' . $name)) {
        throw new InvalidCallException('Unsetting read-only property: ' . get_class($this) . '::' . $name);
    }
}
canGetProperty() public method

Defined in: yii\base\BaseObject::canGetProperty()

Returns a value indicating whether a property can be read.

A property is readable if:

  • the class has a getter method associated with the specified name (in this case, property name is case-insensitive);

}
canSetProperty() public method

Defined in: yii\base\BaseObject::canSetProperty()

Returns a value indicating whether a property can be set.

A property is writable if:

  • the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
  • the class has a member variable with the specified name (when $checkVars is true);

See also canGetProperty().

    return get_called_class();
}
hasMethod() public method

Defined in: yii\base\BaseObject::hasMethod()
